Changes in the Visual Cortex in Patients with High-Tension Glaucoma

Glaucomas keep being defined as a chronic progressive neuropathy with excavation on the optic nerve disc and subsequent changes in the visual field. This formulation does not, however, correspond to the most recent knowledge and has to be revised. Taking a more up-todate approach, glaucoma is defined as a disease in which progressive loss of ganglion cells of the retina and their axons demonstrates itself by changes in the visual field and atrophy of the optic nerve with excavation. However, even this definition emphasising damage to ganglion cells prior to its axons is not complete as it does not indicate damage to the ganglion cells of the subcortical and cortical centres of the brain.
